WEIGHT-POWER'.

SPECIFICATION forming part of Letters Patent No. 370,026l dated September 13, 1887.

Application filed March 23, 1887. Serial No. 232,124. (No model.)

To all whom, it may concern:

Be it known that I, JEROME B. SWEETLAND, of Pontiac, in the county of Oakland, and in the State of Michigan, have invented a certain new and useful Improvement in Veight- Power; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to an improved Inotive power, which is especially designed for operating churns and other like machines; and it consists in the combination, with a helieallygrooved drum rotated by a weight and cord, of a train of wheels, a winding-up device, and a drivingshaft bearing a pinion and detachably connected to the winding-up shaft of the wheel-train by a pin entering an annular groove in said winding-up shaft, all of which will be fully understood from the following description, when taken in connection with the annexed drawings, in which- Figure lis a front view of my improved churn-power. Fig. 2 is an elevation of one side thereof. Fig. 3 is an enlarged diametrical section through the windingdrum, its spurwheels, and bearings. Fig. 4 is a diametrical section through the windingup shaft, its spurwheels, and bearings, and the driving-shaft and its spur-wheel, showing the coupling for the drivingshaft. Fig. 5 is an enlarged sectional detail showing part of the drivingshaft and winding-up shaft and their coupling.

Referring to the annexed drawings by letter, A designates a suitable standard adapted to sustain in a convenient position my improved power, and A designates a rectangular oblong plate, vertically slotted at a a, and adj ustably secured to said standard A by bolts and nuts a a', as shown in Fig. l of the annexed drawings.

B designates a horizontal shaft, Which is journaled in bearings b b, secured to the plate A', and which has keyed on it a pinion spurwheel, c, and a ratchet-wheel, d, between which wheels a large spur-wheel, O, is loosely applied on the said shaft B, and engaged with it by means of a spring-actuated pawl, c', pivoted to the face of wheel C and engaging with the ratchet-wheel d', as clearly shown in Fig.

2. This shaft B, which I denominate the winding-up7 shaft, is adaptedto receive akey on the squared end c. The opposite end of shaft B has an annular groove, f, near one end, and on this end is tted the socketed end of a driving-shaft, E, bearing fast on it a pinion, g. By means ofa screw-threaded pin,f, entering groove f, the shafts B E are connected together so that they can rotate independently of each other, as shown in Figs. 4 and 5. The pinion-wheel c on shaft B engages with a large spur-wheel, F, which is keyed on the elongated hub h of a helically-grooved winding-drum, G, from which depends a rope, w, carrying a suitable Weight, W. This drum G is jonrnaled by its hubs h h in bearings it', rigidly secured to the edges of the plate A', as clearly shown in Fig. 3. The large spur-wheel O, which I have above described as applied loosely on the shaft B and engaged with it by means of a pawl and ratchet-\vheel, engages with apinion spur-Wheel, j, keyed on one end of a shaft, H, which passes freely through the hubs h h of the hollow drum G, and has keyed fast on it alarge spur-wheel, I, which engages-with the pinion g on the drivingshaft E.

It will be seen from the above description that by applying a key or crank on the end e of shaft B and turning this shaft in the direction indicated by the arrow on Fig. 2, the cord w can be wound upon the drum G without overriding, and the weight NV raised. The weight W now acts to rotate the drum G, which, acting through the medium of Wheels F c, shaft B, and the pawl and ratchet, rotates the large wheel C. This wheel in turn transmits rapid rotation to the driving-shaft E, through the medium of pinion j, shaft H, and the large spur-wheel I. The shaft H has a comparatively slow rotation, and it may be utilized for giving motion to a grindstone or other device. By reason of the pin-and-groove eoupling between the drivingshaft E and the winding-up shaft B these two shafts receive one a fast rotation and the other a comparatively slow rotation. The slotsc c through the plate allow the motor to be adj usted higher or lower, as circumstances may require.

Having described my invention, what I claim, and desire to secure by Letters Patent7 1s- IOO 1. The combination, in a Weight-motor, of

`the bearing-plate, the shaft B, journaled in suitable bearings on the said plate and having lkeyed on it the pinion c and ratchet-Wheel d, thespur-Wheel C, loosely secured upon the shaft B and engaging by a spring-actuated pawl with the ratchet-Wheel d, the drum G, journaled in bearings on the plate A and having one of its hubs extended beyond its bearing, the spur-Wheel F, keyed upon the said extended hub of the drum and engaging with the pinion c, the shaft H, passing freely through and having its bearings in the hubs of the said drum, the pinion j, keyed upon the shaft H and engaging with the spur-Wheel C, and the weight and its cord, substantially as described.

2. In a Weight-motor, the combination of the bearing-plate, the shaftB, journaled in bearings on the said plate and having keyed on it the pinion c and ratchet-wheel d, the spur-Wheel C, secured loosely on the shaft B and engaging by means of a spring-actuated pawl with the ratchet-Wheel d, the drum G, journaled in bearings on the bearing-plate V25 and having keyed on one of its Vextended hubs or journals the spur-Wheel F, which engages e With the pinion c, the shaft H, passing freely through the drum G and having its bearings in the journals thereof, the pinion j, keyed 3o upon the shaft E and engaging with the spur- Wheel C, the spur-wheel I, keyed upon the shaft H, the pinion g, having its bearing on and being loosely coupled to one end of the shaft B, the said pinion being located upon a shaft, E, and engaging with the spur-Wheel I, and the weight and its cord, substantially as described.

In testimony whereof I have affixed my signature, in presencegof t'Wo Witnesses, this .24th 4o day of February, 1887.

Itis hereby certified that Letters Patent No. 370,026, granted September 13, 1887, upon the application of Jerome B. Sweetland, of Pontiac, Michigan, for au improvement in Weight-Powers, Was erroneously issued to the said Sweetland as owner of the patent 5 that said Letters Patent should have been issued to Lincoln H. Smith, of Council Blu's, Iowa, as sole owner, he being the assignee of the entire interest; and that the said Letters Patent should be read with this correction therein that thesame may conform to the record of the case in the Patent Ofce.

Signed, countersigned, and sealed this 14th day of February, A. D. 1888.
